Have tried this method and they DONT burn they just crumbled to dust with no heat emission. Tried again with less cement but they crumble when drying and those that gave a big enough lump to handle still wont burn
why not use it for cooking?
Awesome! We get sea coal dust here and though it burns well you waste a lot of it through the grate, this seems like the solution!
These are brilliant I now make them every year. We have very strong winds and these don't burn as fast as coal. A very good way to use up the dust.
This is wonderful, your having to reuse coal dirt while your politicians drive around in their gas guzzling Mercedes Benz. Keep voting.
Well done! Good to see reuse
please,this coal brick can be used in cooking or not.Is there any air pollution or not?
Is this coal brick emissions of sulphurdioxide
one sastistic makes clear the demand placed on the earth by our economic system....every day the world wide economy burns an amount of energy it takes our planet 27 years to produce =10,000 days to grow it and 1 day to burn it........
ignition temps.....lignite 5 kw/kg=160C .....sub bituminous 6.2 kw/kg=170C bituminous 8kw/kg=200 C ........ paper 300C ......sawdust 320C
heat values......1 kg bituminous coal slack =8 kw/kg 1 kg sawdust =6 kw/kg and 1kg of used motor oil (mineral ) oil =12kw/kg paper and and sawdust have simmilar values and cardboard a tad higher ...so you can design your own fuel and know how much each brick is in kw/kg
do not use flour and water as a 1 kg bag flour costs £1 a kilo so would be very expensive way to go
to dispence alltogether with cement....4 parts paper soaked for a week...6 parts sawdust soaked for a week....and can also add 1 part coal dust.....it takes a good 2 days to dry out before you can use it tho............................another formulea is 4 parts coal dust 1 part sawdust and 3 part paper....again you must let it dry out
well soaked paper from junk mail would take the place of cement the glue based ink is a good binder
his ratio is 6 coal 1 sawdust quarter cement,as cement comes in 25 kg bag the formula is...25 kg cement 100kg sawdust 600 kg coaldust...which when you think about it is hardley any cement at all
Hey why not burn your left overs.
This is a good method to make charcoal bricks. But the cement will bring a lot of ash. Is there any good binder to alternate?
we have machine can make it.
